15-943. Base support level

The base support level for each school district shall be computed as follows:

1. The following support level weights shall be used in paragraph 2, subdivision (a) of this section for the following school districts:

(a) For school districts whose student count in kindergarten programs and grades one through eight is classified in column 1 of this subdivision, the support level weight for kindergarten programs and grades one through eight is the corresponding support level weight prescribed in column 2 or 3 of this subdivision, whichever is appropriate:

      Column 1          Column 2       Column 3

       Support Level Weight    Support Level Weight

             For Small Isolated          For Small

   Student Count      School Districts    School Districts

            1-99        1.559       1.399

      100-499     1.358 + [0.0005 x (500 1.278 + [0.0003 x (500

            - student count)] - student count)]

      500-599     1.158 + [0.002 x (600   1.158 + [0.0012 x (600

            - student count)] - student count)]

(b) For school districts whose student count in grades nine through twelve is classified in column 1 of this subdivision, the support level weight for grades nine through twelve is the corresponding support level weight prescribed in column 2 or 3 of this subdivision, whichever is appropriate:

      Column 1          Column 2       Column 3

       Support Level Weight    Support Level Weight

             For Small Isolated          For Small

   Student Count      School Districts    School Districts

        1-99            1.669       1.559

      100-499     1.468 + [0.0005 x (500 1.398 + [0.0004 x (500

            - student count)] – student count)]

      500-599     1.268 + [0.002 x (600   1.268 + [0.0013 x (600

            - student count)] – student count)]

2. Subject to paragraph 1 of this section, determine the weighted student count as follows:

(a)

                                    Support                       Weighted

                                    Level       Student           Student

G            0.007 x           =    

FRPL              0.022 x           =     ________

                  Subtotal    B    

(c) Total of subtotals A and B:                     

3. Multiply the total determined in paragraph 2 of this section by the base level.

4. Multiply the teacher experience index of the district or 1.00, whichever is greater, by the product obtained in paragraph 3 of this section.

5. For the purposes of this section, the student count is the average daily membership as prescribed in section 15-901 for the current year, except that for the purposes of computing the base support level used in determining school district rollover allocations and school district budget override amounts, the student count is the average daily membership as prescribed in section 15-901 for the prior year.
